According to ENERGY STAR, nearly half of the energy used in your home goes to heating and cooling. This makes your HVAC system a prime target for significant savings. Modern systems achieve this with higher SEER ratings, variable-speed technology, and smart thermostats. Even simple upgrades like sealing ducts can boost efficiency by 20 percent, while regular maintenance keeps your current system at its best.
Decoding HVAC Efficiency: What the Ratings and Types Mean
Shopping for an energy efficient HVAC system means encountering acronyms like SEER, AFUE, and HSPF. Think of these ratings like a car’s MPG: a higher number means lower energy bills and greater comfort.
For heating, Annual Fuel Utilization Efficiency (AFUE) shows how much fuel becomes heat. An AFUE of 90% means 90 cents of every dollar you spend heats your home. Heat pumps use the Heating Seasonal Performance Factor (HSPF) to measure their winter heating efficiency. Understanding these ratings helps you make smart, cost-effective choices.
Key Types of High-Efficiency Systems
Heat pumps are versatile systems that move heat rather than creating it. In summer, they move heat out of your house; in winter, they pull heat from the outdoor air and bring it inside. This process is incredibly efficient, especially in moderate climates like Ohio, with modern units achieving SEER ratings of 20-25. Learn more about How heat pumps work.
High-efficiency furnaces have AFUE ratings of 90% or higher, meaning almost all the fuel you buy warms your home. Unlike older models that waste significant heat, these modern units capture nearly all of it. We offer High Efficiency Furnaces that meet these standards.
Ductless mini-splits are ideal for homes without ductwork or for creating comfort zones. By connecting an outdoor unit to one or more indoor units, they provide precise temperature control for specific rooms without the energy loss from leaky ducts. Find the Benefits of Installing a Mini-Split AC.
Central air conditioners today are far more efficient than older models. New systems can achieve SEER ratings around 20, a massive leap from the 7-8 SEER ratings of past units. Upgrading an AC with a SEER below 14.5 could cut your cooling costs in half.
Understanding the Ratings: SEER, AFUE, HSPF, and EER
Here’s a quick guide to what these ratings mean:
| Rating | What it Measures | What a “Good” Rating Means | Analogy |
|---|---|---|---|
| SEER | Seasonal Energy Efficiency Ratio: Cooling efficiency over an entire cooling season. | 14.5 (minimum for ENERGY STAR) – 28 (highest available). A 17+ is a solid choice. | Car’s Miles Per Gallon (MPG) |
| AFUE | Annual Fuel Utilization Efficiency: Heating efficiency for furnaces (how much fuel becomes heat). | 90% or higher (high-efficiency). 85% means 85% of fuel becomes heat. | Report Card Grade (higher is better) |
| HSPF | Heating Seasonal Performance Factor: Heating efficiency for heat pumps over a heating season. | 8.5 (minimum for ENERGY STAR) – 13+. Higher is better. | Heat Pump’s Winter MPG |
| EER | Energy Efficiency Ratio: Cooling efficiency at a single, specific outdoor temperature (95°F). | 13 or more (most efficient systems). Important in consistently hot, dry climates. | Cooling Efficiency Snapshot |
- SEER (Seasonal Energy Efficiency Ratio): This is the most common cooling rating. It measures efficiency over a whole season. Upgrading from an old 7-8 SEER unit to a modern one can double your efficiency. For more details, see What is SEER?.
- AFUE (Annual Fuel Utilization Efficiency): For furnaces, this shows how much fuel becomes heat. A 90% AFUE means 90 cents of every dollar warms your home.
